usb: musb: drop __deprecated flag
Looks like we cannot live without that double_buffer_not_ok
flag due to many HW bugs this MUSB core has.
So, let's drop the __deprecated flag to avoid annoying
compile warnings.

USB: musb: blackfin: work around anomaly 05000450
DMA mode 1 data corruption anomaly on Blackfin systems. This issue is
specific to the Blackfin silicon as the bug appears to be related to the
connection of the musb ip to the bus/dma fabric.
Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105)
DMA mode 1 allows large size transfers to generate a single interrupt
at the end of the entire transfer. The transfer is split up in packets
of length specified in the Maximum Packet Size field for that endpoint.
If the transfer size is not an integer multiple of the Maximum Packet
Size, a short packet will be present at the end of the transfer.
Under certain conditions this packet may be corrupted in the USB FIFO.
Workaround:
Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA
mode 0 to transfer the short packet.
As an example if your transfer size is 33168 bytes and Maximum Packet
Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and
the remainder (33168 mod 512) in DMA mode 0.

usb: musb: Adding musb support for OMAP4430
OMAP4430 supports UTMI and ULPI types of transceiver interface.
In UTMI mode: The PHY is embedded within OMAP4430. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.
There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.
musb driver is register for blocking notifications from the transceiver
driver to get the event notifications for connect/disconnect and ID-GND.
Based on these events call the transceiver init/shutdown function to
configure the transceiver to toggle the VBUS valid, session end and ID_GND
signals to musb and power on/off the internal PHY.
For ID_GND event notifications, toggle the ID_GND signal and then wait for
musb to be configured as "A" device, and then call the transceiver function
to set the VBUS.
In OTG mode and musb as a host, When the Micro A connector used, VBUS is turned on
and session bit set. When the device is connected, enumeration goes through.
When the device disconnected from the other end of the connector(ID is still grounded),
link will detect the disconnect and end the session. When the device is connected back,
there are no events generated in the TWL6030-usb, and link is already down.
So the device is not detected. Removed the session bit disable code which
will recognize the connect of the device.
Limitation: In OTG host mode, if device is connected during boot, it does not get
detected. If disconnect and connect it back or connect after boot only it works.
Fix for this, I will submit seperate patch later.

Also added USB_MUSB_AM35X which is required to differentiate musb ips

purposes,
- Select am35x.c instead of omap2430.c for compilation
at drivers/usb/musb directory. Please note there are
significant differneces in these two files as musb ip
in quite different on AM35x.
Please note that in multi omap configuration only omap2430.c
file will get compiled and we would require to select only
AM35x based board config to compile am35x.c
- Select workaround codes applicable for AM35x musb issues.

USB: make hcd.h public (drivers dependency)
The usbcore headers: hcd.h and hub.h are shared between usbcore,
HCDs and a couple of other drivers (e.g. USBIP modules).
So, it makes sense to move them into a more public location and
to cleanup dependency of those modules on kernel internal headers.
This patch moves hcd.h from drivers/usb/core into include/linux/usb/

* Make smp_lock.h include conditional in hardirq.h

musb: otg timer cleanup
Minor cleanup of OTG timer handling:
* unify decls for OTG time constants, in the core header
* set up and use that timer in a more normal way
* move to the driver struct, so it's usable outside core
And tighten use and setup of T(a_wait_bcon) so that if it's used,
it's always valid. (If that timer expires, the A-device will
stop powering VBUS. For non-OTG systems, that will be a surprise.)
No behavioral changes, other than more consistency when applying
that core HNP timeout.

musb: proper hookup to transceiver drivers
Let the otg_transceiver in MUSB be managed by an external driver;
don't assume it's integrated. OMAP3 chips need it to be external,
and there may be ways to interact with the transceiver which add
functionality to the system.
Platform init code is responsible for setting up the transeciver,
probably using the NOP transceiver for integrated transceivers.
External ones will use whatever the board init code provided,
such as twl4030 or something more hands-off.

musb_gadget: fix unhandled endpoint 0 IRQs
The gadget EP0 code routinely ignores an interrupt at end of
the data phase because of musb_g_ep0_giveback() resetting the
state machine to "idle, waiting for SETUP" phase prematurely.
The driver also prematurely leaves the status phase on
receiving the SetupEnd interrupt.
As there were still unhandled endpoint 0 interrupts happening
from time to time after fixing these issues, there turned to
be yet another culprit: two distinct gadget states collapsed
into one.
The (missing) state that comes after STATUS IN/OUT states was
typically indiscernible from them since the corresponding
interrupts tend to happen within too little period of time
(due to only a zero-length status packet in between) and so
they got coalesced; yet this state is not the same as the next
one which is associated with the reception of a SETUP packet.
Adding this extra state seems to have fixed the rest of the
unhandled interrupts that generic_interrupt() and
davinci_interrupt() hid by faking their result and only
emitting a debug message -- so, stop doing that.

The current MUSB host code doesn't make use of all the available

Change: use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep'
to check the endpoint's business; get rid of the now-unused 'periodic'
array in the 'struct musb'. Also optimize a loop induction variable
in the endpoint lookup code.
